Crown Moulding 7" - 29

This concave crown molding 7" - 29 measures 6.983" width by .813" thickness, allowing the use of four quarter lumber for machining on an industrial-grade molder. The symmetrical terminating profile contains a 3-21/32" cove in the center. A 13/32" line segment flanks the cavetto and joins to two tangent 7/16" radiuses creating an ogee, with a 13/32" tall & wide line on both the top left and bottom right side of the design. The set spring angles are at forty-five degrees; these dedicated back bevels keep the face side of the profile parallel to the wall and ceiling when installed; they also lock in the positioned height at 4-15/16" tall with a projection of 4-15/16" across the top.

Review our commentary about axial constant positioning for crown bevels, the article will help you dial this profile in axially provided the machine is properly calibrated. Three high points in the pattern layout were deliberately positioned on the same plane, our disciplined design features will assure excellent hold down conditions while milling as long as the pressure shoe is parallel to the machine bed-plates.

A brief detailed explanation on how to use the calculator is located here. If you would like some assistance with the dimensions, print a copy of our fraction - decimal - millimeter chart, place it on the molder or around the shop to help machine operators save time and increase accuracy during setup procedures.

Width = 7.000" / Depth of Cut = .470" (top knives).

Thickness = .813" / Depth of Cut = .544" (right blades) & .544" (left cutters).
